RUser guideAdjustingTo achieve the best reaming results a tool with zero run-out is desirable. In order to compensate for anyerrors due to run-out from the tool holders or the machine spindle, the following holders are recommendend:compensation holders, hydraulic chucks, or shrink fit holders. DR reamers can be measured with differentmethods:Through insert holder short taperWith the reamer disassembled measure directly on the insert holdersshort taper. High accuracy, simple handling. This is the most accurate andpreferred method.Through circular landMeasuring directly behind chamfer angle on external insert diameter.All interface errors are eliminated. This is the preferred method for smalldiameter inserts.On the external diameter of the insert holderDR tool holders are manufactured very accurately on all diameters. A methodeasy to handle that offers reasonable measuring results.Shanks with integrated compensation deviceThese shanks with integrated comp. must be used for reamingdiameters bigger than 35 mmR28In the UNITED STATES call us toll free1 - 888 - 818 HORN
